The working principle of induction is based on electromagnetic induction. When an electrically conductive material is placed in a rotating magnetic field, an electromotive force is induced across the conductor. This phenomenon is known as electromagnetic induction. In the case of induction motors, this induced electromotive force generates a current in the rotor, creating a magnetic field that interacts with the rotating magnetic field generated by the stator. This interaction produces a torque, causing the rotor to rotate.
Induction heating works on a similar principle of electromagnetic induction. In this process, an electrically conductive metal is heated by generating eddy currents within the metal through electromagnetic induction. As the eddy currents flow against the resistivity of the metal, heat is generated through the principle of Joule heating. The heat produced is proportional to the square of the current multiplied by the electrical resistance of the metal.
In the case of induction furnaces, the principle of electromagnetic induction and the Joule effect are utilized. The energy transfer to the object to be heated occurs through electromagnetic induction. When an electrically conductive material is placed in a variable magnetic field, induced electric currents, known as eddy currents, are generated, which eventually lead to Joule heating. Joule heating is the process by which the passage of an electric current through a conductor releases heat. The heat produced is proportional to the square of the current multiplied by the electrical resistance.
In induction heating units, an alternating current is applied to the primary of a transformer, creating an alternating magnetic field. When the secondary of the transformer is located within the magnetic field, an induced current is generated. In a basic induction heating setup, an inductor (usually a copper coil) acts as the primary of the transformer, and the part to be heated becomes the short-circuiting secondary. When a metal part is placed in the inductor and enters the magnetic field, circulating eddy currents are generated inside the part, leading to heating.
Induction heating is a non-contact process that offers advantages such as fast and efficient heating, precise temperature control, and uniform heating. It is commonly used in applications such as melting, heating, and welding in various industries. The basic concept behind induction heating involves the generation of a magnetic field through a coil of conductive material and the use of electromagnetic induction to induce currents in the object to be heated, which results in the generation of heat.
